This is not a scale bug. This is how the POSIX spec specifies
the computation. The "10 * 2.1" ends up doing the computation
with an effective scale of 1 ignoring the scale variable.
In the division, that one uses the scale variable.
This is not documented as well as possible in the manual page.
I'll try to fix it. (doc bug)
